%X On July 11, 2008, the aviation flight test of widas (wide angle infrared dual-mode line / area array scanner) was carried out in the intensive observation area of Linze grassland. Widas is composed of 4 CCD cameras, 1 mid infrared thermal imager (AGEMA 550) and 1 thermal infrared thermal imager (S60). It can simultaneously obtain data of 5 angles of visible / near infrared (CCD) band, 7 angles of mid infrared band (MIR) and 7 angles of thermal infrared band (TIR). The main variable of ground synchronous observation is surface temperature This data can provide a basic data set for surface temperature inversion and verification of airborne satellite remote sensing data.The data synchronization quadrat includes 120m × 120m quadrat and 30m × There are two kinds of 30m encrypted small quadrats. In the intensive observation area of Linze grassland, the surface temperature of quadrat a (reed land), quadrat B (saline alkali land), quadrat C (saline alkali land), quadrat D (alfalfa land) and quadrat e (barley land) are measured by hand-held infrared thermometer. During the measurement, continuous measurement shall be carried out along the northeast direction. This data set includes the excel table of surface temperature measurement data of 5 quadrats. See metadata "Heihe integrated remote sensing joint experiment: layout of quadrat transects in Linze grassland densified observation area" for the distribution information of quadrat transects.
